IW4052B ANALOG MULTIPLEXER DEMULTIPLEXER High-Performance Silicon-Gate CMOS The IW4052B analog multiplexer/demultiplexer is digitally controlled analog switches having low ON impedance and very low OFF leakage current. Control of analog signals up to 20V peak-to-peak can be achieved by digital signal amplitudes of 4.5 to 20V (if VCC - GND = 3V, a VCC - VEE of up to 13 V can be controlled; for VCC - VEE level differences above 13V a VCC - GND of at least 4.5V is required). These multiplexer circuits dissipate extremely low quiescent power over the full VCC -GND and VCC - VEE supply-voltage ranges, independent of the logic state of the control signals. When a logic “1”is present at the ENABLE input terminal all ORDERING INFORMATION channels are off. IW4052BN Plastic The IW4052 is a differential 4-channel multiplexer having two IW4052BDW SOIC binary control inputs. A and B, and an enable input. The two TA = -55° to 125° C for all binary input signals select 1 of 4 pairs of channels to turned on packages and connect the analog inputs to the outputs. • Operating Voltage Range: 3.0 to 18 V • Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C • Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply 2.0 V min @ 10.0 V supply 2.5 V min @ 15.0 V supply PIN ASSIGNMENT LOGIC DIAGRAM Double-Pole, 4-Position Plus Common Off FUNCTION TABLE Control Inputs ON Enable Select Channels B A L L L Y0 X0 L L H Y1 X1 L H L Y2 X2 L H H Y3 X3 H X X None X = don’t care PIN 16 =VCC PIN 7 = VEE PIN 8 = GND 1 IW4052B MAXIMUM RATINGS* Symbol Parameter Value Unit VCC DC Supply Voltage (Referenced to GND) -0.5 to +20 V VIN DC Input Voltage (Referenced to GND) -0.5 to VCC +0.5 V VOUT DC Output Voltage (Referenced to GND) -0.5 to VCC +0.5 V IIN DC Input Current, per Pin mA ±10 PD Power Dissipation in Still Air, Plastic DIP+ 750 mW SOIC Package+ 500 PD r Dissipation per Output Transistor 100 mW Tstg Storage Temperature -65 to +150 °C 260 TL Lead Temperature, 1 mm from Case for 10 °C Seconds (Plastic DIP or SOIC Package) * Maximum Ratings are those values beyond which damage to the device may occur.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused digital pins must be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused Analog I/O pins may be left open or terminated. 2 IW4052B DC ELECTRICAL CHARACTERISTICS Digital Section Sym bol Parameter Test Conditions VIH VIL IIN ICC Minimum High-Level Input Voltage, Channel-Select or Enable Inputs Maximum Low -Level Input Voltage, Channel-Select or Enable Inputs Maximum Input Leakage Current, Channel-Select or Enable Inputs Maximum Quiescent Supply Current (per Package) VIS=VCC thru 1kΩ VEE=GND IIS<2µA on all OFF Chanels RL=1kΩ to GND VCC Guaranteed Limit V ≥ -55 ≤ 25 ≤ 125 Unit °C °C °C V 3.5 3.5 3.5 5 7 7 7 10 12 11 11 15 VIS=VCC thru 1kΩ VEE=GND IIS<2µA on all OFF Chanels RL=1kΩ to GND 5 10 15 1.5 3 4 1.5 3 4 1.4 3 4 V VIN=VCC or GND 18 ±0.1 ±0.1 ±1.0 µA Channel Select = VCC or GND 5 10 15 20 5 10 20 100 5 10 20 100 150 300 600 300 0 µA DC ELECTRICAL CHARACTERISTICS Analog Section Symbol RON ∆RON IOFF Parameter Maximum Resistance Test Conditions “ON” VEE=GND=0 VIS = GND to VCC Maximum Difference in VEE=GND=0 “ON” Resistance Between Any Two Channels in the Same Package Maximum Off- Channel VEE=GND=0 Leakage Current, Any One Channel Maximum Off- Channel VEE=GND=0 Leakage Current, Common Channel 3 5 10 15 5 10 15 Guaranteed Limit ≥ -55 ≤ 25 ≤ 125 °C °C °C 1050 1300 800 550 400 310 320 240 200 10 15 5 - 18 ±100 ±100 ±1000 18 ±100 ±100 ±1000 VCC V Unit Ω Ω nA IW4052B AC ELECTRICAL CHARACTERISTICS(CL=50pF,Input tr=tf=20.0 ns) Guaranteed Limit VCC Symbol Parameter V ≥ -55 ≤ 25 ≤ 125 °C °C °C 120 60 60 5 tPLH, Maximum Propagation Delay , Analog 60 30 30 tPHL Input to Analog Output (Figure 1) 10 40 20 20 15 RL=200kΩ 1440 720 720 5 tPLZ, Maximum Propagation Delay , Address 640 320 320 10 tPHZ to Analog Output (Figure 2) RL=10kΩ 480 240 240 15 VEE=GND=0 VEE=-5V 5 450 450 900 1440 720 720 5 tPLZ, Maximum Propagation Delay, Enable to 640 320 320 10 tPZL Analog Output (Figure 2) RL=10kΩ 480 240 240 VEE=GND=0 15 VEE=-10V 5 400 400 800 900 450 450 5 tPHZ, Maximum Propagation Delay, Enable to 420 210 210 10 tPZH Analog Output (Figure 2) RL=10kΩ 320 160 160 VEE=GND=0 15 VEE=-10V 5 300 300 600 CIN Maximum Input Capacitance, Channel7.5 7.5 7.5 Select or Enable Inputs CI/O Maximum Capacitance VEE=GND=-5V 5 5 CIS COS 5 18 Feedthrough CIOS 5 0.2 - 4 Unit ns ns ns ns pF pF IW4052B ADDITIONAL APPLICATION CHARACTERISTICS Sym VCC bol Parameter Test Conditions V BW Maximum On-Channel VEE=GND, RL=1kΩ 10 Bandwidth or Minimum 20 log(VOS/VIS)=-3db Frequency Response (-3db) VOS at Common OUT/IN VOS at Any Channel 10 VEE=GND (-40db) Feedthrough Frequency (All RL=1kΩ 10 Channels OFF) 20 log(VOS/VIS)=-40db VOS at Common OUT/IN VOS at Any 10 Channel (-40db) VEE=GND, RL=1kΩ Signal Crosstalk Frequency 20 log(VOS/VIS)=-40db Between Sections : - Measured on Common - Measured on Any Chanel THD Total Harmonic Distortion VEE=GND 5 fIS=1kHz sine wave 10 15 Address-or Enable to Signal VEE=GND, RL=10kΩ** 10 Crosstalk tr,tf=20ns, Square Wave * Peak-to-peak voltage symmetrical about (VDD-VEE)/2 ** Both ends of channel Figure 1.
